One of the first things mentioned by new Seattle Mariners general manager Jerry Dipoto upon his hiring was how the club lacked general depth, particularly in the upper minors. Many clubs welcomed impact and contributing rookies to their rosters this past season. But Seattle’s inability to develop talent at the higher minor league levels during Jack Zduriencik’s tenure nearly left the Mariners out of the aptly named ‘year of the rookie’ in 2015.
We knew that pieces surrounding the core would need to be augmented and practically all executives talk about a need for depth. There’s no secret: the Mariners are a team with holes. We saw how the offense fizzled behind a slumping Robinson Cano in the first half and the pitching staff was exposed throughout the season. When Mike Zunino struggled, there was no Plan B.
Dipoto’s first deal as general manager, a six-player trade with the Tampa Bay Rays, took a step towards rebuilding the starting pitching depth. Nate Karns is coming off a 26-start rookie campaign but will turn just 28 in a few weeks. As Prospect Insider’s Jason A. Churchill noted, Karns could start the season in the bullpen or in the back end of the rotation. In some ways he gives the M’s more flexibility with Vidal Nuno — both are rotation and bullpen candidates or one could be sent to Triple-A to get stretched out early in 2016. Nuno is likely a better fit in the bullpen, though.
PI’s Luke Arkins recently covered the pitching needs in depth. Taijuan Walker and James Paxton are leading rotation candidates with Roenis Elias and Mike Montgomery next on the depth chart. Montgomery is out of options meaning he would be exposed to waivers if sent down but Elias can still be sent down. Beyond them the rotation depth In Tacoma is slim to none with Sam Gaviglio and Jordan Pries atop that list. Top pitching prospect Edwin Diaz is likely another year or more away from being major league ready.
Smith has graduated to the big league squad and despite some struggles this past season, figures to start the year in a start-up role. C.J. Riefenhauser figures to take Danny Farquhar‘s spot in the bullpen, only from the left side, so no additional depth was added there. With Charlie Furbush recovering from a slight tear in his rotator cuff, the southpaw depth could be tested with David Rollins and Rob Rasmussen also in the picture.
Tony Zych made his major league debut in September and in 13 appearances, including one start, he pitched a 2.04 FIP and 11.79 strikeouts per nine over 18 and 1/3 innings. He should have the inside track on one of the middle relief gigs. Mayckol Guaipe, J.C. Ramirez, and Jose Ramirez are other names to keep an eye on. None of the three have the upside of a Smith, for example, but do provide some bullpen depth. Cody Martin is also among the right-handed options after being picked up on a waiver claim.
Over on the infield, Seattle is set at second and third base long-term. The trade of Brad Miller suggests the club is confident in Marte and his ability to be a starter. The 22-year-old had a strong debut producing a 112 wRC+ while offering solid and improving defense.
Chris Taylor now finds himself No. 2 on the shortstop depth chart but struggled offensively in 2015. He’s hit well enough at Triple-A in recent memory, but at least offers a reliable glove in a key defensive position. Shawn O’Malley made a decent impression during his September cameo displaying on-base skills and picking up three stolen bases. Perhaps his best asset is his positional flexibility. Tyler Smith has also taken some steps forward and could become an option in the second half.
D.J. Peterson appeared to be readying for show time one year ago, but it was a difficult year for the top prospect and he’ll likely begin 2016 at Triple-A. It’s a similar story for Patrick Kivlehan who had a slightly down year offensively in his first taste of Triple-A action. Both are nearing major league readiness and provide nice depth at the infield corners for the second half. And of course, there’s the perennial name squeezed between the major league and Triple-A depth charts, Jesus Montero.
Behind the plate the story is the same as it was in 2015. Zunino may still need time in Triple-A to continue restructuring his swing and Jesus Sucre and John Hicks have proven that they aren’t offensively capable for the majors. It’s no secret that catching is a major concern for the Mariners.
James Jones and Stefen Romero are joined by Boog Powell in the outfield depth chart. Powell has a shot at breaking camp as the club’s starting centerfielder given his contact and defensive skills but the other two should start the year in Tacoma at this point. Daniel Robertson was claimed off waivers from Dipoto’s previous employer, the Los Angeles Angels. The 30-year-old spent the majority of 2015 at Triple-A where he posted an underwhelming 83 wRC+ but has solid plate discipline skills.
The most glaring position of weakness for the Mariners is at catcher, but that’s nothing new. Around the infield Seattle appears to be in reasonable shape depth-wise. Dealing Miller hurts, but the addition of a veteran infielder would allow Taylor to potentially start the year at Triple-A, making the depth look better.
The outfield is susceptible with Seth Smith being the only real major league caliber outfielder on the depth chart. Powell, Jones and Romero are considerations for the open spots as we speak, but if all three were to make the club, Flores and Robertson would make up the Triple-A depth. That could be scary.
You always need more pitching depth so that much goes without saying. The bullpen was a major issue for Seattle in 2015 and with all the pieces dealt over the past year, is in need of a makeover. It’s hard to evaluate the starting pitching given how many question marks there are. A combination of Walker, Paxton, Karns, Nuno, Elias, and Montgomery figure to take two rotation spots and probably a couple bullpen spots as well.
Not every position needs to have a bonafide starter or back-up caliber player at Triple-A, but the presence of legitimate options will be a welcomed change. Remember, it doesn’t take much for depth to appear. A couple solid minor league signings, a couple prospects taking a step forward, and a couple surprises can quickly change the tone in how we reference the players in Tacoma.
It’d be unfair to expect Dipoto and his staff to fix every problem the M’s currently face in year one, but rebuilding the catching and outfield positions while stockpiling arms would be meaningful progress. The pitching staff already looks stronger than it did at season’s end.
The first steps have already been taken with many more to come.
